[1 120 105- HAC'KMAJVN United States Patent 3 382,126 METHOD AND APPARATUS FQR TRANSFERRING DATA WITHIN AN ENCLOSURE David B. Hackrnann, 13708 Susan Lane, BurnsvillaMinn. 55378 Filed Feb. 24, 1965, Ser. No. 434,803 12 Claims. (Cl. 156-240) ABSTRACT OF THE DISCLQSURE This disclosure relates to a method and apparatus for transferring data within an enclosure. The method includes stacking a plurality of sheets in an envelope enclosure which has a window opening therein and with printed data on at least one of the sheets which is to be transferred to at least another of the sheets in the enclosure, the printed data being exposed through the aperture in the envelope in the stacked relationship. The method includes applying heat and pressure by a roller to the enclosure at the aperture to transfer data within the enclosure. The apparatus includes structure for stacking the plurality of sheets in a predetermined relationship, inserting them into an envelope enclosure with the sheet having the data to be transferred positioned adjacent an aperture in the enclosure and moving the enclosure along a track and into engagement with a heated roller which applies the pressure thereto to effect the transfer of data within the enclosure.

The present invention relates to data transferring apparatus and more particularly to an improved method and apparatus for transferring data within an enclosure.

Transfer of data between sheets, one of which contains a mirror image of the data to be transferred is a recognized method of duplication of information. Such processes normally use a variety of methods of transfer including heat and pressure and have found increased usage in modern record keeping, data handling, mass mailings and with the use of automatic equipment for the same. Further, with the use of computer type data storage units, address type data is needed to facilitate withdrawal and input of information into the storage units.

The particular method and apparatus of transferring data within an enclosure is specifically adapted for use in connection with mass mailings where it is desired to transfer from one piece within an enclosure, such as a letter type envelope, information afiixed on an address appearing in an open window of the envelope to a second piece within the envelope and positioned below the piece hearing the address. In such mass mailings, information from the various addressees may come from an addressograph, lists or information stored within the computer and it is desired that the return mail bear the same information as that appearing on the address to facilitate handling of the same. Such information is automatically printed on a single fill sheet of an envelope to be inserted into the envelope as the address appearing on the same through an open window. Along with such sheets may be receipts, billings, return envelopes, and the like which are usually inserted into the envelope along with the addressed sheets. Printing of similar information on two or more pieces and the necessary correlation of similarly addressed sheets so that they arrive in the same envelope in a filling operation requires extremely complex machinery. Generally, the filling operation has to be performed manually. The use of having similarly marked pieces within an envelope facilitates tabulation of return mail and the input of information into the storage and computing devices.

In the present method, only a single piece is addressed but it is printed from a suitable addressing machine to ice include various coded information, if desired, and the surface of the addressed piece will appear in direct image with a mirror image on the opposite side of the sheet. With this technique, another piece to which the addressed information is to be attached may be inserted into the envelope adjacent the addressed piece and below the same. The improved method and apparatus herein includes applying a heated wheel to the envelope after the pieces are inserted therein to transfer the information appearing on the mirror image side of the addressed piece to the next adjacent piece in the envelope. Thus, it may print as a part of a return address from the addressee on the'return envelope information which will facilitate sorting, cataloging and the like when the return envelope is used and again received at the sending source. Depending upon the type of fill inserts, it is possible to transfer such information to one or more pieces within the envelope merely by the application of heat and pressure thereto.

It is therefore the principal object of this invention to provide an improved method of transferring data within an enclosure.

Another object of this invention is to provide an improved apparatus for transferring data within an enclosure.

A further object of this invention is to provide an apparatus in the form of a heated drum which is moved in contact with an envelope type enclosure and spring biased therewith to apply a pressure to the envelope to facilitate transfer of information within the envelope.

Another object of this invention is to provide an apparatus in which the heated drum is selectively operated to apply heat and pressure to an enclosure such as an envelope to effective transfer of data between sheets therein.

A further object of this invention is to provide in an apparatus of this type an improved means for applying heat and pressure and uniformly moving the envelope enclosure to apply heat only to desired portions therein.

These and other objects of this invention will become apparent from a reading of the attached description together with the drawings wherein:

FIGURE 6 is a sectional view of the drum taken along the lines 66 of FIGURE 4,

FIGURE 7 is a side elevation view of a heated drum together with a solenoid drive assembly for the transfer apparatus, and

FIGURE 8 is a schematic view of the electrical circuit for the heated drum.

The improved method and apparatus for transferring data within an enclosure is shown generally in plan view in FIGURE 1 incorporated with a conventional envelope filling and sealing machine. In FIGURE 1, this structure is shown in plan View as incorporating only two filler stations, a stacking station, and an insenter station to be later identified. The drive mechanism for performing the stepping function of these stations and the advancing an envelope to a station where the fill stacks are inserted is omitted for simplicity. It will be understood, however, that a plurality of such filler stations and modifications in the envelope drive may be incorporated and that various types of envelope filling machines currently available on the market may be used for this purpose. One such machine is manufactured by the Bell & Howell Company, Inserter Division, Phillipsburg, Pa., and is identified as a 12C, 6 Station Inserter. For the purposes of the present disclosure and to show the improved method herein, the filling and sealing machine is identified generally at 10 as incorporating a table or base part 12 below which would be positioned drive and sequencing apparatus (not shown). Positioned on the base 12 are a pair of upstanding guide frames 15 and 18 which are located adjacent a stacking channel 20 having a chain drive 22 associated therewith. The chain drives include material advancing flanges 24 in spaced relation thereon and the chains are continuous in extent (not shown) being looped under the table or base portion 12 and moved through suitable guide means in a stepped sequence. At the end of the stacking channel 20 is positioned a stacking station having a supporting framework 32 thereon in which the fill sheets in a stacked relationship are positioned after being released by the clamps 24 on the chain drive 22. Material, that is the fill sheets, are taken from the respective stations 15 and 18 by individual withdrawal means (not shown), such as suction cups, and moved into the stacking channel 20 underneath positioning guides 35, 38 pivotally mounted on the shaft 36. The individual pieces or inserts move from the stations 15, 18 and as they are advanced toward the channels 20 are grasped by grip members 40 pivoted on a shaft 42 and moved into the channel 20 to be engaged by flanges 24 on chain drives 22. In order of the sequence in which the fill sheets are to be stacked, the last station 15 adjacent the stacking station 30 will have its sheet inserted on top of the stack and such sheet will carry the data to be viewed through the opening or window of the envelope on top of the stack. Further, the next adjacent station, that is station 18 will supply the insert piece onto which the data is to be impressed such as the return envelope, and will position the insert piece in contacting and adjacent relationship underneath the addressed or data carrying sheet. As will be seen in FIGURE 1, only a portion of the machine is shown, it being understood that a number of stations, for example six in number, would be included for supplying sheets to the stacked assembly. The individual shafts 36 and 42 operating respectively the grippers and the holddown for the stacks will be so moved or rotated through linkages connected to the shafts in a predetermined sequence so as to permit the insert sheets to be taken from the respective stations as the stack of inserts is positioned adjacent the same and held in the stacked relationship as the material is advanced along the conveying line or channel 20. As previously indicated, the details of this machinery is omitted since it is conventional and the Bell & Howell Company, Inserter Division, model 12C, 6 Station Inserter is an example of apparatus of this type.

Also included on the base or table 12 is a second channel or conveying apparatus, identified at Slit, which includes a chain type conveyer with envelope securing clamps 52 attached thereto. The conveyer originates from an envelope stack station 55 having associated brackets 57 forming the same. A stack of envelopes, indicated at 60, are positioned within the frame 57 and suitable envelope removing means (not shown), such as suction cups at the base of the table, remove an envelope from the stack and positions it relative to the chain and a clamp 52 positioned thereon such that the clamp may move the envelope along the conveying line. As the envelope leaves the envelope stack station 55, it encounters a flap opener 62 positioned on the surface of the table and overlying an envelope conveying line 50 which opening flange engages the edge of the envelope and opens the same holding the envelope flap open as the envelope is advanced down the conveying line. At an inserting position or station 65 on the table 12 opposite the stacking station 30 the material in the stack station is inserted into the envelope.

The inserting station has positioned above the same a yoke carrying suction cups which are adapted to open the envelope to facilitate insertion of material therein. The stacked material from the stack station 30 is moved translationally to the channel 20 and toward the inserting position 65 through suitable guide brackets 76 which slide the stack of material over guide fingers 78 and into the interior of the envelope as the yoke 70 with suction cups 75 thereon opens the envelope. In this position, the flap to the envelope is held beneath the guides 71 to facilitate the insertion of the material therein. The transverse movement of the guide brackets 76 in the insertion of the material is controlled through suitable drive means (not shown) which drive means is sequenced with the movement of the envelopes on the chains 50' toward the inserting station such that an envelope will be positioned at the inserting station 65 as the stack of insert material from the stack station 30 is advanced by the guide brackets 76 toward the same. Suitable interlock means (not shown) are normally included at this station to indicate that an envelope is in position before the guide brackets 76, through associated drive means, are permitted to move the stack material toward the inserting station.

As this material is inserted, the addressed data printed on the top fill sheet is inserted adjacent the top surface of an envelope, which is indicated at 80, in FIGURES 2 and 3, and adjacent a window opening 82 therein. Thus, as will be seen in FIGURE 2, a top fill sheet 84 with the addressed data, indicated at 85, thereon is positioned over the second fill sheet or return envelope 86. The information data taken from any storage device, such as addressegraph or equivalent source, is imprinted on the fill sheet 84 in such a manner that it appears as a direct image on one surface thereof and as a mirror image in inked form in the opposite surface thereof adjacent the next fill sheet, such as the envelope 36. Further, the envelope 86 is so inserted that its flap portion 90 will be underneath the mirror image such that the mirror image may be transferred thereon as a direct image. As will be seen in FIG- URE 2 also, envelope 86 is so positioned that the data will be printed thereon reversed from the normal return address location and so the special envelope includes a legend 92 to indicate the position from which the return address information is to be read. It will be obvious that in place of a return envelope, any type of fill sheet may be used which upon return to the sending source may be used for tabulating information as an input to suitable storage devices. The particular envelope shown herein has a flap portion 95 which is opened in the inserting machine by the characterized fiange 62, and this flap portion faces toward the front or address side of the en velope. Thus in the assembled condition of the envelope, the window 82 with the addressed portion of the insert appearing therein, will be on the same side of the envelope as the flap portion which is folded down on the same. The flap portion of the envelope also provides the surface which is stamped or franked, as indicated at 99. In addition, the return address for the envelope 80 may be imprinted on the flap portion, as at 100.

The stacked material, such as the return envelope 86 and address insert sheet 84, will thus be inserted into the envelope at the inserting station 65 through movement of the flanges 76 and associated guides advancing the insert sheets into the envelope which is held deflected open slightly by the yoke 70 with the suction cups 75 thereon. After the material has been inserted into the envelope, the conveying chain 50 through the clamp bracket 52 thereon advances the envelope to a heating station having a heated roller or drum 112 positioned over the same which is adapted to be brought into contact with the surface of the envelope at the opening 82 therein and into direct contact with the addressed portion 85 of the fill sheet 84 to transmit material from the mirror image thereon to the next adjacent piece or insert, such as the return envelope 86 within the envelope. As the envelope is moved under the heated drum 112 at the heating station 110, a brush 113 moistened through a fluid line 114 from a reservoir 115 moistens the gummed label preparatory to sealing the envelope. A flange or cammed surface 116 positioned adjacent the brush and behind the same folds the moistened gummed flap over and applies pressure to the same such that the envelope is sealed as the data is being transferred therein through application of heat and pressure to the contents of the envelope.

The final station 120 on the filling and inserting apparatus includes the release and stacking position in which the envelopes are moved under a stack of previously printed and sealed envelopes through movement of the clamps 52 thereon and positioned at the bottom of the pile of stacked envelopes between a pair of positioning flanges to hold the stack of sealed envelopes in an assembled relationship preparatory to removal from the machine. The stack is elevated as each envelope is brought into the released position through suitable means (not shown).

The apparatus included at the heating station 110 is shown in detail in FIGURES 4, 5, 6 and 7. This improved apparatus, when added to the conventional filling and inserting machine and synchronized therewith and through the use of special address inserts which are inked on two surfaces thereof provides a means for transferring data within an enclosure to eliminate the problem of sorting and keeping in a desired arrangement similarly addressed or marked data sheets to be inserted into a common envelope. Thus, as will be seen in FIGURES 4, 5, 6 and 7, the table 12 has a pair of upstanding flange members 130, 131 suitably mounted and secured thereon which pivotally mount or journal a yoke member 133 near the upper extremities thereof through a suitable pivot pin 135. The yoke member has bifurcated extremities 136, 137 with suitable tapped apertures therein to mount a shaft 141 the shaft carrying slip rings 144 thereon, for purposes to be later noted. Shaft is suitably journaled in the bifurcated extremities 136, 137 of the yoke 133 and projects beyond the bifurcated portion to mount the heated drum 112. In the sectional view in FIGURE 6, it will be seen that the extremity of the shaft has mounted thereon a plate 145 forming an end part of the heated drum 112 which has a cylindrical outer surface portion 146 and an interconnecting portion, such as is indicated at 148. The outer surface portion is mounted on the plate 145 through suitable means, such as screws 15%, threaded into tapped apertures 152 in the plate 145. The interconnecting portion 148 and outer cylindrical portion 146 are formed integral and are made of a metal having a high heat conductivity, such as aluminum, for the transfer of heat from an electrical heating element, such as a Calrod element indicated at 160, mounted on the interconnecting portion 148 through an insulating screw member 16.2 threaded into the portion 148, as at 164. As will best be seen in FIGURE 6, shaft 146 is hollow, as at 166, as is the insulated screw member 162, at 167, for the purpose of providing a passage for electrical conductors to the slip rings 14% from the Calrod element and a thermostat control, shown in block at 179, and mounted on the interconnecting portion 148 through screw means 172.

FIGURE 8 shows a schematic circuit diagram of the electrical connections through the thermostat element which includes a suitable temperature responsive means 174 or bimetal operating relay 175 with contacts 176 therein to control flow of current from an electrical source to the elements of the Calrod heating element 160. Thus, as is indicated in FIGURE 8, the electrical source is connected through the slip rings 144 and through the conductors, indicated at 18%} in FIGURE 6, to the thermostat element which includes the contactor, as shown in FIGURE 8. The relay 175 is connected across one side of the electrical source, preferably of the alternating current type and having a grounded conductor 182 such that the relay will be energized upon closure of the temperature responsive means 174 to operate the relay contacts 176 to the closed position. Whenever this bimetal senses a temperature beyond a predetermined setting, its contacts will open, disconnecting the heating elements 160 from the power source. In this manner the heated drum is maintained at a predetermined temperature suflicient to transfer data from the ink medium on the addressed sheet 84 to the next adjacent fill sheet in the stacked position within the envelope. A cover 185 positioned over the drum encloses the thermostat for protection purposes. The electrical conductors are connected to terminals positioned in an insulating block 188 and connected across the extremities of the bifurcated portions 136, 137 above the shaft 140 of the yoke 133. The insulating block 188 is suitably secured thereon and this mounting permits flexible conductors to be connected to the terminal posts 186 from the electrical source (not shown), to permit movement of the yoke 133 relative to the upstanding flanges 130, 131 mounted on the base 12.

The yoke 133 is pivoted toward and away from the surface 12 of the table through a shaft member 190 threaded into the yoke 133 and secured therein by a lock nut 192. The opposite extremity of the shaft mounts a tooth pinion through a pivot pin 198 such that the pinion 195 is free to rotate thereon. Positioned over the pinion is a chain 200 secured at one extremity to a flange type bracket 202 mounted on a lower base 210 in the filling and inserting apparatus or inserter. The opposite extremity of the chain 206 is connected to the armature 205 of an eiectromagnet whose coil 206 is similarly mounted on the base 210 through suitable screw means 212. Brackat 262 has a second upstanding portion, as indicated at 213, which serves as an out stop for the armature 205 of the electromagnet to limit the travel thereof. As the armature 205 is withdrawn into the confines of the electromagnet or coil 206 upon energization of the same, the extremity of the chain 200 is moved with the armature 205 to pivot or move the shaft 109 and pivot the yoke 133 mounting the drum 112 toward and away from the surface 12 of the inserting machine. A suitable aperture in the table (not shown) permits such movement. Also positioned on the undersurface of the table 12, as will be seen in FIGURES 4 and 7, is a second shaft 200 which shaft is mounted in trunnion members 221, 222 secured to the undersurface of the table through suitable bolt means 225, and positioned below the axial extent of the shaft 140 within the yoke 133. The shaft 220 mounts a sprocket member 230 having a chain 233 positioned thereon to cause the shaft 221} to be rotated in the journals 221, 222. Although not shown, it will be understood that the chain 233 will be connected to a rotary drive portion of the inserter apparatus to continuously rotate with energization of the machine. The free extremity of the shaft 220 mounts a second cylindrical drum 235 which is aligned with the cylindrical outer surfac 146 of the heated drum 112 and is adapted to be engaged thereby as the yoke 133 is pivoted on the upstanding flanges 130, 131.

Also shown in phantom in FIGURE 4 is a limit switch 240 with a sensing finger 243 connected thereto which finger operates the switch 240 upon the presence of an envelope in front of the finger. The switch 240 controls the energization of the solenoid 206 to deflect the yoke 133 relative to the surface 12 of the table such that the heated drum will approach and be positioned adjacent and in near contacting relationship with the lower drum 235 continuously driven from the shaft 220 and through the chain 233. Thus, whenever an envelope is moved by the chain 50 into engagement with the sensing finger 243, the solenoid 206 is energized deflecting the yoke 133 and bringing the heated roller in contact with the envelope. The speed of rotation of the shaft 220 approximates the speed of movement of the chain 511 such that the movement of the heated drum surfaces against the envelope will cause frictional engagement and rotation of the drum 112 within the yoke portion 133 as the envelope is advanced under the surface of the drum 112. The pivotal movement of the yoke 133 with the drum thereon will apply a pressure to the surface of the envelope and the heated surface 146 thereof will roll over the window portion of the envelope to heat the portion of the insert in line therewith and transfer the data thereon through transfer of the inking material on the mirror image side of the same to the next adjacent fill sheet within the envelope.

The application of heat and pressure to the surface of the sheet bearing the data to be transferred will cause transfer of the data within the enclosure to a second sheet therein so that there is no need for separate handling of these sheets or any specialized equipment for insuring that both sheets arrive in the same envelope. It will be understood that in the present disclosure, the data being transferred is located adjacent the window of an envelope which is to be directly contacted by the heated roller. It will be recognized, however, that depending upon the types of ink, pressure applied, and the envelope material that such direct contact is not always required. Further, it will be recognized that a number of fill sheets may be placed within an envelope with certain of the sheets having desired information tabulated thereon and with a mirror image of the same on the opposite surface of the sheets such that it may be transferred to a next adjacent sheet positioned within the envelope. Thus, the improved invention should not be considered as limited to the transfer of address information to a return envelope but can be applied to varying types of data and as effecting transfer of data between several sheets within an enclosure through the application of heat and pressure.

In the operation of the improved data transferring apparatus with the improved method, it will be seen that a plurality of insert sheets may be positioned in a stacked relationship through a conventional machine and in a predetermined order such that a fill sheet to which data is to be transferred will be located adjacent the fill sheet upon which the data is imprinted in both a direct and mirror image of the same. Further, it will be recognized that the improved apparatus may be use varying shapes of envelopes, with or without the window therein, although for maximum efiiciency a window envelope with the information to be transferred as well as for the purpose of directing the envelope is most efficient. The stacked fill sheets are directed into the envelope through conventional apparatus and with the material inserted in the envelope, the envelope is directed under a heated roller which is pivoted into contact with the same for a limited period of time to effect an application of rolling pressure and the application of heat to the surface of the envelope and across the areas upon which data is printed to effect a transfer of data between sheets within the enclosure. The improved apparatus may vary in size and shape and different types of filling and inserting machines may be incorporated therewith to which the heat transfer apparatus, that is the pivoted and heated drum for applying pressure to the enclosure may be applied. In the present disclosure the filled envelope will have the envelope flap moistened and folded to close the envelope simultaneously with the application of heat and pressure thereto to thereby eliminate any special handling and any manual operation for the insertion of two or more pieces having identical material thereon into the envelope.

While I have shown the method and apparatus of the present invention as applied to transferring of address type data between an address fill sheet and a return envelope within an envelope, it will be recognized that additional data and different types of information may be included therewith, or in place thereof, to facilitate the imprinting of the data for any desired mailing or accounting function and the receipt of return information to be automatically tabulated.
